I am not insulting anybody, least the admirals.
It was an honest comment in terms of coming to terms with something new and sometimes un-tried. Nothing wrong in that.
If we look at a 'swarm' of e-boats and a 'swarm' of submarines focused on limiting transfer of troops and stores from Britain to France, we could perhaps see a different outcome in the very early days?
It is also correct that the early aircraft were very lightly armed (if at all). It would have been difficult to shoot down a German airship. only much later did the British have different bullets for that job.
However, if we look at the channel routes, it is hard to protect against 'swarms' of e-boats. The question is then: with what to combat low-cost e-boats? bigger British units could be hit as well, not just transports.
It would not be a great proposition to exchange a cruiser for an e-boat.
Operating submarines in the channel is not easy. Too shallow too often, but not impossible.
... and that is my contribution: Let the HSF re-evaluate what is important. And that might be to: (1) reduce cross-channel traffic (2) open the distant blockade of Germany
To say that the HSF should " get an admiral who can grasp a new concept!" clearly implies that they did NOT have an admiral who could grasp a new concept. To say that Scheer, Hipper etc could not grasp new concepts sounds very much like an insult; grasping new concepts was part of their job.
The evidence seems clear thar the German navy's top brass COULD grasp new concepts. They ran the first modern sub campaign, they created a fleet that did quite well in the first major clashes of capital ships at sea for a lifetime, they ran the first real strategic bombing campaign, and the HSF's major leaders, Scheer and Hipper, had both made their careers in the fairly unproven new weapon of torpedoes. They grasped the new concept of torpedoes so eagerly that the German destroyers' design concentrated on torpedo rather than gun power - and then Jutland proved that torpedoes were actually much LESS effective in surface warfare than conventional big guns. The HSF fleet admirals may have grasped the new concept too deeply to see its very real limitations.
The British had bullets that could shoot down airships from September 1916, which means that these expensive weapons had a fairly short life becoming very vulnerable.
The "swarm of e boats" concept (which wasn't really new, of course) never really worked in any war. It's arguably something favoured only by people who haven't spent much time at sea and who don't understand the very harsh realities of life in a small vessel rolling and bouncing through swells, with all the accompanying problems of sighting, vision, and handling weapons and sensors. There's a reason that the navies increased the size of their small torpedo craft almost continually - the small ones didn't really work.
"It looks so simple to those who have had the special features of craft like the C.M.B.'s explained to them to visualise the boats out night after night sinking and destroying. But it was not one night in twenty on the Belgian Coast that they could operate with success, and then the targets were few" wrote Admiral Bacon of the Dover Patrol, which had extensive experience in MTBs and motor launches and found them very much lacking. In fact he was concerned that using them merely alerted the enemy to possible attacks from more effective larger vessels. Since he was there and we are not, perhaps we should not imply that people like him were incapable of grasping new concepts - he grasped the concept but was open-minded enough to see when it didn't work.
The Germans built coastal torpedo boats just for working the Belgian and Channel coasts during the war. The first series was about 25% bigger than a WW2 E-Boat and they had little success for heavy loss. The later series got bigger and bigger because of the problem of small vessels in reality. As Bacon noted,
"As a matter of fact, on one occasion only out of those on which I called on the C.M.B.'s suddenly to take a chance opportunity did the weather permit of their operating ; on the others the weather prevented them from doing so. They always gallantly tried, but the overpowering forces of Nature intervened."
A swarm by e-boats was no more likely to cause significant damage than the years of German attempts with larger craft. Bacon claims that only "one-thousandth part of I per cent" of the vessels escorted by the RN's Dover Patrol were lost, and that the cross-Channel traffic they escorted passed "5,600,000 troops across without an accident to a single man". That was despite heavy attacks by German destroyers and torpedo boats and considerable U-Boat traffic.
